They revealed during SDCC the first portion of the Phase 4 lineup today going from 2020-2021. It includes 5 movies and 5 tv shows:

Black Widow - May 1, 2020

A prequel that explores her past featuring Taskmaster. 

The Eternals - November 6, 2020

Not much known aside from huge cast with people like Salma Hayek, Angelina Jolie, etc. 

The Falcon and the Winter Soldier (Disney+ series) - Fall 2020 

A series starring both of them that also features the return of Zemo from Civil War. 

Shang-Chi and the Legend of the Ten Rings - February 12, 2021

Starring Simu Liu in the role and has the actual Mandarin in the movie. 

Doctor Strange in the Multiverse of Madness - May 7, 2021

Has fucking SCARLET WITCH in it (YES, was hoping for this) and is the first MCU horror film according to director Scott Derickson. 

Loki - Spring 2021 (Disney+ Series) 

A series that "explains where Loki went after Endgame", according to Kevin Feige. So alternate timeline I guess?

WandaVision (Disney+ Series) - Spring 2021

Set after Endgame, and first appearance of Monica Rambeau.

Thor: Love and Thunder - November 5, 2021

Female thor storyline, return of Natalie Portman. Directed by Taikia Watiti again. 

Hawkeye (Disney+ Series) - Fall 2021

Hawkeye series with him training Kate Bishop. 

What If...? (Disney+ Series)  - Summer 2021 

A what if series narrated by Jeffrey Wright as The Watcher.

Then there's the announced/mentioned but not dated:

Played by Mahershala Ali, the Blade reboot is coming. 

Then Captain Marvel 2, Black Panther 2, Fantastic Four, X-men, and Guardians of the Galaxy Vol. 3 were confirmed to be in development. 

I'm HYPED. Only disappointment for me was no Ant-Man 3 announcement, that's the only one that was suspiciously absent during the announcements. It better be in there eventually! 

Should be noted that Falcon & the Winter Soldier, Wandavision, Hawkeye, Loki, and What If?..., are going to be TV shows for Disney's upcoming streaming service, Disney+.

With that said, out of these films, I am very much looking forward to Black Widow, Black Panther 2, and Guardians 3.

Oh yeah, I thought that was already well known enough for people to know already but i'll mention it just in case :P 

I mostly don't care any more. Maybe some of these new ventures will be really good.....but it's from creatively bankrupt Disney/Hollywood. I expect safe, by-the-numbers pablum, infused with varying degrees of pandering, forced, agenda driven identity politics. Yay. Thank the angry ghost of Ed McMahon I rediscovered anime.

Well, looks like I'll have to get Disney+ additionally to Netflix then.

Anybody knows when the service will start in Europe?

Disney is killing it!!! (In a good way lol)

If I remember right it'll start in the first months of 2020

Meh. MCU is mostly done for me.

I'm not interested in any of the movies but the What If series intrigues me. I'm more of a DC comics reader but Marvel's What If issues I used to read back in the day were awesome. They had all sorts of wacky, awesome scenarios like "What If Magneto won?" and my favorite "What if the Punisher got the Venom symbiote?".

I can't imagine it being a high quality show if they make live action though. It should be animated but for adults to make the most of all the ideas they could use.
